"I have an old floor furnace that needed to meet PGE standards before gas could be turned back on. He insured that it was and re established gas flow. Hardly anyone would touch it and I was without it for over 2 years. Not only did Matt fix it within an hour, but also restored electrical power in my garage in a separate issue. Highly recommended. Not cheap, but if you want quality, Kazen HVAC is a name you can trust to get it done right in a most expeditious manner."

"Robert and his crew were timely, professional and did a great job with the install. Robert went above and beyond the call of duty. Because of personal circumstances in my life I had some anxiety about handling this type of homeowner business. Robert was kind and caring. He not only did a great job replacing my furnace but helped to patiently ease my mind along the way. I felt good supporting a small local business too."

"The technician at Ridgeback was able to fix a mini-split we had installed by another company 3 years ago. The company that installed it refused to fix it and offered to install another unit if we paid for it. They were terrible to deal with so it was a pleasure to find a company that was dependable and good at getting the job done. I would highly recommend Ridgeback to anyone!"

FAQs for furnace / forced air heating system install or replace projects in Saint Helena, CA

Converting from an oil furnace to an electric furnace isn't a simple swap—the oil system needs to be completely removed before installing the electric furnace. You'll need a full electric system installation, but you might be able to reuse existing ductwork if it's up to current safety standards. You’ll need to budget for a new electric furnace installation, which costs between $1,800 and $6,200, including professional removal, proper disposal, and safe installation of the new system.

Electric furnaces are 100% efficient at converting electricity into heat. However, some of that heat can be lost as it travels through your home's ductwork or escapes through poorly insulated areas. That's why regular duct maintenance and proper home insulation are important to maximize your furnace's efficiency and reduce heat loss, ensuring consistent warmth and lower energy costs.

With proper maintenance, an electric furnace can last anywhere from 20 to 30 years, outlasting the average gas furnace's lifespan of 15 to 20 years. To keep your electric furnace running efficiently, schedule regular cleanings, tighten connections, and have inspections done before winter arrives. With routine maintenance, you’ll ensure consistent, safe heating for years to come.

The size of the electric furnace you need depends on factors like your home's square footage, climate, and insulation quality. As a general guideline, those who live in warmer climates should multiply their square footage by 30 to 35 BTUs, while those in cooler areas should multiply it by 50 to 60 BTUs.

Consulting with an HVAC professional can help you determine the exact size that's right for your home.

An electric furnace works by converting electricity into heat using high-resistance heating elements. A blower then pushes the warm air through your home's ductwork, distributing heat evenly throughout your space. Since there's no combustion involved, electric furnaces eliminate the risks associated with gas furnaces and provide consistent, reliable heating when properly installed.

An electric furnace uses between 40 and 80 kilowatts per day to heat your home. The exact amount it uses depends on factors like your home's size, insulation, and overall energy requirements. Larger homes or those with poor insulation use more energy than smaller, well-insulated spaces. A professional furnace assessment can help confirm the ideal unit size for your needs.
